Summa/bo@ 'vide means for preventing damage to the HOWARD PHILLIS, OF DETROIT, MICHIGAN.

ELnvAToR-GATE SHOE.

Application led November 4, 1918.

y To all whomc't may concern:

Be it known that I, HOWARD PHILLIPS, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented new and useful.

used for operating the gates.

The principal object of the invention-is to provide automatic means' for moving the shoe into operative position to open the gates when the car is stopped.

Another object of the invention is to proparts if the gate operating means should fail to act for any reason.

The invention also' consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in theY appended claims.

In describing my invention in detail, reference .will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in whichz- Figure l is a diagrammatic View showing my invention in use.

Fig. 2 is an enlarged View, partly in section of the invention.

Fig. 3 is a front view of the shoe. Fig. 4 is a detail view of a modification.

y invention is adapted for use on elevators where the gates are'operated by a separate machine. A draw bar 1 runsfthe full length of the shaft and this draw bar is vertically movable by the before mentioned machine. Slots 2 are cut in the draw bar at each floor and a shoe 3, carried by the car is used to press a pawl 4 intothe slot to raise the gate. These elements are well known in the art and will notbe described in detail.

My invention relates to meansgfor auto'- matically moving the shoe linto position to lstrike the pawls when the car stops at any particular floor, the said shoe being normally out of Contact with the paWls.

In carrying out myinvention I pivot the shoe 3 to the arms 5 and these arms are hinged to a part of the car, as at 6. I prefer to provide one of the arms with a knuckle joint, as at 7. A solenoid 8 is suitably con- Specication of Letters Patent.

iiected with the car between the arms, and the coil of this solenoid is electrically connected with the starting and stopping mechanism of the car. The sliding core 9 of the solenoid is connected with one of the arms 5 by means of the link l0. The other arm, the one provided with'the knuckle joint, is connected with the end of the solenoid by a coil spring 1l. It will be seen that when the solenoid is denergized the spring will force the shoe outwardly away from the car, when said shoe will be in a position to engage the pawls to force them into engagement with the gates. Assoon as the car is started the solenoid will be energized so that the core will be drawn inwardly to move the arms against the tension of the spring and thus move the shoe into inoperative position.

By my invention the cai' will run smoothly without noise and the shoe and pawls are not subject to wear. The knuckle joint will allow the shoe to collapse if the same should strike any obstruction, and thus not bend the arm. This construction of'arm will alvlow the device to be used without the solenoid.

lVhen desired, or necessary, I provide means for limiting the outward movement of the solid arm 5. I do this by means of al This arrangement yof parts is shown in' Fig. 4. A

It is thought from theforegoing description that the advantages and novel features of my invention will be readily apparent.

`I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope oi"y the appended claims.

I claim as my invention l. A device of the class described, com prising a shoe, a pair of arms hinged to the car and pivotally connected with the shoe, one ofV said arms being formed of two parts, a knuckle Vjoint connecting the two parts togther, a solenoid carried by the c ar and having its coil electrically connected with the starting means of the car, a core for'the solenoid, a link connecting the 4saine with the solid arm and a coil spring connecting onev f of the part-s of the sectional arm with a part of the solenoid. f

2. A 'device of the class described, comprising a shoe, a pair of arms hinged to the ca sind pivotally' Connected with the shoe, one of said zii-ins being foi-ined of two parts, :i knuckle joint Connecting the two parts t0- gether? :l solvnoid Carried by the cur and having its voiielectiic'nily connected with the starting means of the cui', u core forth@ solenoid, ulink connecting theA Same with the solid arm, :l coil sp1-ing connecting oneY of the parts of the sectional zum with :1 part oi 10 the Solenoid, and adjustable inelans for limiting' the outward movement of the solid arm.

In testimony whereof affix my Signatura.

HOWARD PHILLIPS.
